Is an arm really better than a tentacle? Apparently the people who came up with the prosthetic tentacle thought it would be more useful. The design and usage is very simple of course since it can only perform basic grips and actions. It is definitely a nice change of pace from simply getting a normal prosthetic arm. A regular prosthetic arm is usually quite complex to use and may not be as versatile as a tentacle, plus the idea behind this tentacle is simply innovative. I personally feel it is a bit creepy to have, but it would definitely be an eye catcher anywhere you go. My hat is off to the people who have come up with this great idea.
